19 June 1998 - Renumbering

0549 was added before previous 6-digit numbers of the 8xxxxx and 9xxxxx
series. For example, 8xxxxx became 05498xxxxx with the numbering change
of 19 June 1998.

Subscriber numbers beginning with the digit '3' were expanded to 12 digits.
The special purpose of these numbers, if any, is unknown, although
this range is associated with mobile numbers in Italy, which surrounds
San Marino.
